Can use the wire distal ends of numerous types.Fig. 9 to 11, Figure 14 to 14A, Figure 15 to 15A, Figure 16 to 16A, Figure 17 to 17A, Figure 18 to 18A, Figure 19 to 19A, Figure 20 to 20A, Figure 21 to 21A, Figure 22 to 22A, Figure 23 and Figure 24 show several instances.

Fig. 9 shows an embodiment offilament 33, and it has a near-end 50, a far-end 52, and this far-end is to comprise onefirst section 54, onesecond section 56 and one the3rd section 58 by near to order far away.Can betweenmain shaft 51 andsecond section 56, extend forfirst section 54 and can be biased to one first angle, this first angle is limited betweenmain shaft 51 andfirst section 54 and less than 180 degree.Can betweenfirst section 54 and the3rd section 58, extend forsecond section 56 and can be biased to one second angle β, this second angle is limited betweenfirst section 54 andsecond sections 56 and less than 180 degree.Can extend to a free end and can be biased to one the 3rd angle γ fromsecond section 56 for the3rd section 58, the 3rd angle is limited betweensecond section 56 and the3rd section 58 and less than 180 degree.

Second angle can be greater than first angle.First angle and the 3rd angle sum deduct second angle can be at about 70 degree to the scope of about 110 degree.First angle and the 3rd angle sum deduct second angle can be at about 80 degree to the scope of about 100 degree.First angle and the 3rd angle sum deduct second angle can be about 90 degree.

The3rd section 58 length offilament 33 can be less than the internal diameter of sheath 32.For example, the3rd section 58 length can be equal to or less than less than the length of 0.028 inch or itsheath 32 internal diameter 2/3.

Can be less than 0.3 inch from the central axis ofmain shaft 51 to the measured vertical dimension of free end.First section 54 andsecond sections 56 length separately can about 0.2 inch to about 0.3 inch scope, perhaps about 0.24 inch to about 0.26 inchscope.First section 54 length can about 0.248 inch to about 0.25 inch scope, and second section length be about 0.25 inch to about 0.252 inch scope.In one embodiment,first section 54 length can be 0.249 inch, and second section length is 0.2504 inch.

The far-end 52 offilament 33 can comprise at least two linearity ranges, their relative to each other directed angles that is in a non-zero.Have at least two linearity ranges and can allow the far-end of filament to fill in sheath and do not contact the wall of sheath, and it can also allow the main shaft of filament to extend along blood vessel wall, and the end of filament (for example the 3rd section) thrusts blood vessel wall.

According to the purposes of expection, be positioned at the configuration that the filament end of far-end 52 can have numerous kinds.Wire shape can be " atraumatic ", and the meaning is that its shape can be adapted such that insert action causes the very little spasm that perhaps do not cause perhaps to damage to blood vessel.For example, Figure 10 shows the far-end 52 that stops with a hemispherical free end.This hemispheric end can be veined or mechanically or chemically changed to produce rough surface.Other atraumatic ends can comprise have the full circle arc, or bend to J-shaped, or only be the end of a curved shape.

Figure 10 shows an atraumatic end, and this end has alongfilament 33 from hemispherical shape a sleeve pipe to the proximal extension offilament.Sleeve pipe 70 can be gained in strength for far-end, thereby increases scraping power and increase contact surface long-pending to prevent the disengaging ofhemispheric end 72.

In other embodiments, far-end 52 can be " aggressive " and by bending or warpage so that its scraping blood vessel wall.Fig. 9 shows has flat free-ended far-end 52, has sharp edges around this free end.Can also be through the edge bevel be constituted an aggressive far-end 52 to constitute cusp.Far-end with cutting blade (wing as shark is the same) also can be aggressive.Far-end 52 can carry out roughened, cuts and/or cause blood vessel wall generation spasm so that far-end has more aggressivity ground.

Coarse surface can form through abrasion, machined, sandblast, for example acid corrosion of chemical attack (for example nitric acid, Fluohydric acid., hydrochloric acid and/or sulphuric acid) through the steel that make otherwise smooth.Coarse outer surface can also produce to produce surface irregularity through rolled metal plate (for example forming the plate of sleeve pipe 70) on the guide member that is shaped brokenly at.

The outer surface of first section equally,, second section and/or the 3rd section can apply a kind of grinding agent so that rough surface.Other surface treatments can comprise coarse file type and diamond grit.For example, the diamond of No. 30 granularities can produce aggressive surface, and the diamond of No. 200 granularities can produce non-attacking surface.

In use, the filament that especially has a roughened tip can periodically be wrapped in the sheath to help to remove from the filament end the normal operation of chip and holding device again.

Spiral shell tooth through deferring to difformity (for example square, rhomboid, trapezoidal, parallelogram, ellipse, triangle or pentagon) is introduced a thread contour with one second filament along the length offilament 33, and it is surperficial onfirst section 54 and/orsecond sections 56 offilament 33, to form a kind of aggressivity.

Figure 10 shows an embodiment, and it has onefirst section 56, and this first section has asleeve pipe 70, and this sleeve pipe has a coarse outer surface that is produced with one of mentioned distinct methods in front.Except showing roughened surface treatment, Figure 10 has further showed the single line silk that has increased weight at far-end, and this weight is to be increased by the sleeve pipe that has rough external surface in this situation.This weight can concentrate on the filament or eccentric location.An eccentric weight can be so that filament swing everywhere in rotary course.Compare with the filament that increase the weight of at the center, this swing effect can have more aggressivity ground disturbance blood vessel.

The far-end 52 offilament 33 can also comprise a bending section.The curvature of this bending section can be constant, and perhaps it can defer to other curves, and is for example oval or avette one section.The far-end 52 offilament 33 can also have a straight section in this bending section distally.Be similar to the embodiment with constant curvature, the curvature that has this bending section of straight section can be constant, and perhaps it can defer to aforesaid shape.

Spring 90 can carry out attached to produce an aggressive cutting surface alongfirst section 54 and/orsecond sections 56 from the far-end 52 of filament 33.Can carry out brazing in a plurality of ends to spring.Spring 90 can be deferred to aforesaid differently contoured.Figure 11 to 13 shows the cross sectional view of the spring of deferring to square, trapezoidal and pentagonal spiral shell tooth respectively.

The wedge angle of differently contoured (for example, square, triangle, parallelogram, pentagon) can thrust in the blood vessel wall and the excision blood vessel wall.According to the purposes of expection,filament 33 can have hemispheric or flat free end.Hemispheric end or flat free end can also be veined or roughened.
